OK or NG

OK: ADP steering wheel tilt switch circuit is OK.
NG: GO TO 2.

CHECK ADP STEERING WHEEL TILT SWITCH HARNESS CONTINUITY
1. Disconnect automatic drive positioner control unit connector and ADP steering wheel tilt switch.
2. Check continuity between automatic drive positioner control unit connector M33 terminals 1, 17 and ADP steering wheel tilt switch connector M16 terminals 2, 3.
  - 1 (W/G) - 2 (W/G): Continuity should exist.
  - 17 (G/B) - 3 (G/B): Continuity should exist.
3. Check continuity between automatic drive positioner control unit connector M33 terminals 1, 17 and ground.
  - 1 (W/G) - Ground: Continuity should not exist.
  - 17 (G/B) - Ground: Continuity should not exist.
OK or NG
- OK: GO TO 3.
- NG: Repair or replace harness.
